Description

Technical Field

[0001] The invention relates to the technical field of child seats, in particular to a child safety seat with a wrapping buffer mechanism. Background Art

[0002] Child safety seats are fastened to car seats and installed on the back seat for children to sit on and have restraint devices. In the event of a car collision or sudden deceleration, the impact force on the child is reduced and the child's body movement is restricted to reduce injuries and maximize the safety of the child. However, the wrapping property of the buffer mechanism of existing child safety seats is not strong, that is, it only considers the effective protection of children when the car suddenly decelerates and collides with the front and back, but does not consider the effective buffer protection of children when the vehicle collides sideways. In addition, sideways collisions are generally more serious collisions. If strong buffer protection cannot be performed, it will cause very serious injuries to the child or even the death of the child. Summary of the invention

[0042] When the lateral impact force acts on the buffer contact plate 4, it will push it to move in the direction of the seat body 1. As the buffer contact plate 4 moves, the buffer linkage frame 47 will be pushed to move under the action of the buffer connecting rod 46, and then the first buffer spring 49 will be deformed to play the role of the first layer of buffering. As the buffer contact plate 4 moves, the linkage matching rod 53 will push the connecting block 5 to move downward, which will cause the second buffer spring 52 to deform and play the role of the second layer of buffering.

In addition, a first buffer elastic sheet 31 is provided on the upward buffer guard plate 3, which can play an auxiliary buffering role, further improving the protective effect of the upward buffer guard plate 3. The upward movement of the upward buffer guard plate 3 is realized by the upward spring 35, so that it can react quickly and move to the protective position. In addition, as the connecting block 5 moves downward, Under the action of the inclined push-up strip 28, the contact matching column 59 will be pushed to move, thereby causing the supporting connecting plate 58 to move until the supporting connecting plate 58 is separated from the overlapping bottom plate 64. In this way, under the action of gravity, the counterweight movable bar 6 will move downward quickly to respond, and then under the action of the driving connecting rod 63, the protective buffer plate 7 will be pushed out of the movable groove 22 to block both sides of the child's head. A second buffer elastic sheet 72 is provided on the protective buffer plate 7, which can further enhance the protective effect of the protective buffer plate 7.
